Abstract:A series of multiaxial ratcheting experiments has been conducted on 63Sn-37Pb solder alloys. It is shown that the ratcheting rate in each loading step keeps constant under constant axial stress and cyclic shear strain range. However, the ratcheting rate is sensitive to the shear strain rate. Based on the Edmunds-Beer (E-B) equation, a simple constitutive model is proposed to predict the ratcheting rate of each loading step. The results have shown that the model can predict the experimental data well.
